“Our hearts are with the victims of the Santa Fe High School shooting, and with all victims of gun violence. In light of today’s tragedy, we are cancelling the 13 Reasons Why S2 premiere event tonight,” Netflix said in a statement.

Nine students and a teacher were killed Friday morning at Santa Fe High School in Santa Fe, Texas, when a 17-year-old allegedly opened fire with a shotgun and a revolver. The alleged shooter is in jail facing capital murder charges, sheriff’s officials said.
13 Reasons Why, based on showrunner Brian Yorkey’s adaptation of the best-selling novel, revolves around the unexplained suicide of Hannah Baker — which was shown up close — and the 13 audiotapes she left behind for her classmates.

The series’ season 2 storyline revolves in part around a thwarted school shooting.

In preparation for the launch of Season 2, Netflix announced it had added new resources to 13ReasonsWhy.info, including an updated Discussion Guide and a new Discussion Series — a set of videos where cast members address issues in the series including bullying, sexual assault and drug abuse.

The added resources came in response to criticism by some mental health experts who say the show, which deals with teen suicide, bullying, drunk driving and rape in graphic detail, could pose health risks for certain young people, especially those with suicidal thoughts.
